DevExtreme jQuery/JS - Resize and Relocate

To change the size of the Popup, specify the height and width options.

HTML
JavaScript
<div id="popupContainer">
    <p>Popup content</p>
</div>
$(function() {
    $("#popupContainer").dxPopup({
        title: "Popup Title",
        visible: true,
        height: 300,
        width: 500
    });
});

To allow an end user to resize the Popup, assign true to the resizeEnabled option.

JavaScript
$(function() {
    $("#popupContainer").dxPopup({
        title: "Popup Title",
        visible: true,
        resizeEnabled: true
    });
});

If you need to position the Popup against a specific element on your page, set the position option.

JavaScript
$(function() {
    $("#popupContainer").dxPopup({
        title: "Popup Title",
        visible: true,
        position: {
            my: "left",
            at: "left",
            of: "#targetElement"
        }
    });
});

This configuration of the position option reads as follows: "place my left side at the left side of the "#targetElement".

By default, an end user is allowed to change the Popup position only on desktops. To enable this feature on other devices too, set the dragEnabled option to true. Note that the user drags the Popup by its title, so the title should not be hidden.

JavaScript
$(function() {
    $("#popupContainer").dxPopup({
        title: "Popup Title",
        visible: true,
        dragEnabled: true
    });
});
NOTE
Dragging is possible only if the "height: 100%" style is applied to the <html> element and "min-height: 100%" - to the <body> element.
